| titleOfInvention | A kind of preparation method of carbon quantum dot decorated n-n type MFe12O19/CeO2 magnetic separation photocatalyst |
| abstract | The invention discloses a preparation method of an n-n-type MFe 12 O 19 /CeO 2 magnetic separation photocatalyst modified by carbon quantum dots. Glucose is used as a raw material to synthesize carbon quantum dots in a reaction kettle; Salt or cerium salt is used as raw material, and chelating agent, anti-gel collapse agent, acrylamide and cross-linking agent are gradually added, and acrylamide and cross-linking agent are polymerized under the action of the field to form a gel; the gel is dried. , sintering and other processes to synthesize MFe 12 O 19 or CeO 2 nanoparticles; stir an appropriate amount of carbon quantum dots, MFe 12 O 19 and CeO 2 nanoparticles in an alcohol solution with ultrasonic stirring, pour off the supernatant, dry it, and transfer it to Sintering in a box furnace, adjusting the ratio of the three to obtain an n-n-type MFe 12 O 19 /CeO 2 magnetically separated photocatalyst with controllable photocatalytic activity of carbon quantum dots. The invention has low cost and easy synthesis, and overcomes the shortcomings of low charge separation efficiency and difficult recovery of traditional photocatalysts. |
